Answer:
Option A.
Step-by-step explanation:
While proving a number to be irrational, we usually start with the assumption that the number is rational . In the same way here , we will assume the opposite of the inequation to be proved , that is, x < 3 .
Answer:
0.3
Step-by-step explanation:
x÷0.4=2 1/9 ÷3 1/6
x÷0.4 = 19/9/19/6
x/0.4 = 19/9 ×6/19
x/0.4 = 114/171
cross multiply
171x = 114×04
171x = 45.6
divide by 171
171x/171 = 45.6/171
x=0.266
x=0.3 approximately
Answer:
$5333.33
Step-by-step explanation:
x is the unknown, but we know that 22.5% of x equals 1,200. So we use this information to set up an equation.
x * 22.5% = 1,200
Now we can solve for x by dividing both sides by 22.5%
x = 5333.33
The dollar value of the items she sold was $5333.33
Answer:
Being proportional between two entities, refers to the 'Constant of Proportionality' that would be fixed between them which establishes a relationship between them when multiplied or divided.
If we considered it on a graph, the 'Constant Of Proportionality' may take any real values between the coordinate pairs x and y [x,y]. As even 0 is a real number, it will surely be a constant of proportionality when multiplied since its product would result in itself (0). Hence, both x and y turns 0.
As the coordinates of the origin are always (0,0), the graph (Or the slope) would surely pass through the origin.
Example :
If we consider a graph such that x=y.
And if we multiply or divide any real number (a) between them.
ax=ay
As a is a variable, and can take the value of 0, the graph can pass through the origin as x and y nullify becoming the coordinates of the origin.
